* ps3disk: passing wrong variable to bvec_kunmap_irq()Dan Carpenter2010-10-121-1/+1

* Fix pktcdvd ioctl dev_minor range checkDan Rosenberg2010-09-281-1/+1
| | | | | | | | | | | | | | | | | The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a pktcdvd_device from the global pkt_devs array. The index into this array is provided directly by the user and is a signed integer, so the comparison to ensure that it falls within the bounds of this array will fail when provided with a negative index. This can be used to read arbitrary kernel memory or cause a crash due to an invalid pointer dereference. This can be exploited by users with permission to open /dev/pktcdvd/control (on many distributions, this is readable by group "cdrom").

* cciss: freeing uninitialized data on error pathDan Carpenter2010-09-211-1/+1
| | | | | | | | | | | | | | The "h->scatter_list" is allocated inside a for loop. If any of those allocations fail, then the rest of the list is uninitialized data. When we free it we should start from the top and free backwards so that we don't call kfree() on uninitialized pointers. Also if the allocation for "h->scatter_list" fails then we would get an Oops here. I should have noticed this when I send: 4ee69851c "cciss: handle allocation failure." but I didn't. Sorry about that. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

| * cciss: disable doorbell reset on reset_devicesStephen M. Cameron2010-08-231-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The doorbell reset initially appears to work correctly, the controller resets, comes up, some i/o can even be done, but on at least some Smart Arrays in some servers, it eventually causes a subsequent controller lockup due to some kind of PCIe error, and kdump can end up leaving the root filesystem in an unbootable state. For this reason, until the problem is fixed, or at least isolated to certain hardware enough to be avoided, the doorbell reset should not be used at all. Signed-off-by: Stephen M.

The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.

It is possible to reset them independently, however, they share a battery backed cache module. One of the pair controls the cache and the 2nd one access the cache through the first one. If you reset the one controlling the cache, the other one will not be a happy camper. So we just forbid resetting this conjoined mess. Signed-off-by: Stephen M.

Smart Array controllers newer than the P600 do not honor the PCI power state method of resetting the controllers. Instead, in these cases we can get them to reset via the "doorbell" register. This escaped notice until we began using "performant" mode because the fact that the controllers did not reset did not normally impede subsequent operation, and so things generally appeared to "work". Once the performant mode code was added, if the controller does not reset, it remains in performant mode. The code immediately after the reset presumes the controller is in "simple" mode (which previously, it had remained in simple mode the whole time). If the controller remains in performant mode any code which presumes it is in simple mode will not work. So the reset needs to be fixed. Unfortunately there are some controllers which cannot be reset by either method. (eg. p800). We detect these cases by noticing that the controller seems to remain in performant mode even after a reset has been attempted. In those cases we ignore the controller, as any commands outstanding on it will result in stale completions. To sum up, we try to do a better job of resetting the controller if "reset_devices" is set, and if it doesn't work, we ignore that controller. Signed-off-by: Stephen M.
